Naturally, Hyuga Kagami did not believe Otsutsuki Toneri would successfully evolve a Tenseigan as smoothly as he had in the original timeline.
Because he and Otsutsuki Toneri had reached the same conclusion: Hyuga Hiashi's Byakugan was not the purest or most powerful pair within the Hyuga Clan.
Hyuga Kagami's genetic solution had been created by taking advantage of his assignment as a medical rescuer during the Third Shinobi World War to collect the genes of nearly every member of the Hyuga Branch Family. Only after adding the genes of Hiashi, the clan head, had he barely managed to gather all the hidden gene sequences.
In other words, as clan head, Hiashi merely happened to possess the few crucial gene sequences missing from Hyuga Kagami's genetic solution. That did not necessarily mean he was the member of the Hyuga Clan with the most hidden gene sequences.
Judging by talent, the second daughter of the Main Branch, Hanabi—Hinata's younger sister—was currently the Hyuga clansman with the most hidden gene sequences apart from Hyuga Kagami.
Otsutsuki Toneri had evidently noticed this as well.
In the original timeline, Otsutsuki Toneri had arranged to meet Hiashi, yet showed no intention of taking Hiashi's Byakugan. This indicated that Hiashi's Byakugan had not been his first choice.
It was clear, then, that Otsutsuki Toneri had attacked the Hyuga Clan and taken Hiashi's Byakugan only because circumstances had forced his hand.
Based on this, Hyuga Kagami believed that Otsutsuki Toneri's attempt to evolve a Tenseigan would likely not go as smoothly as it had in the original timeline. If Otsutsuki Toneri was unlucky and he and Hiashi could not piece together all the hidden gene sequences, the evolution might even fail.
After all, Hyuga Kagami's genetic solution had fused the genes of nearly the entire clan. It was
